Results of the combined and radiation treatment of tongue cancer patients with various anatomical forms of the tumor

: A significant correlation between benz(a)pyrene concentration in soil and potato tubers was established for its soil level of 0.6-50.0 mg/kg. This points to potato uptake of the carcinogen even at low levels of pollution. Absence of correlation between benz(a)pyrene concentrations in grain (husk) and soil even for relatively high levels of soil pollution (up to 320 micrograms/kg) shows that wheat and millet grains do not absorb the carcinogen.
